SPECIFICATION forming part of Letters Patent No. 273,652, dated March 6,1883.

7 Application filed November 21, 1882. (ModeL) To all whom it mayconcern:

Be it known that I, ORSON HARVEY WHEEL- ER, of Oharlesworth, in thecounty of Eaton and State of Michigan, have invented a new and ImprovedInjector, of which the following is a full, clear, and exactdescription.

My improvements relate to steam-injectors for lifting and forcing water;and the invention consists in certain features of construction andarrangement, having the object to force a solid stream of waterunder-any pressure of steam, and also to prevent any accumulation ofsediment inthe injector, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional-elevation of my improved boiler-feeder. Fig. 2is a cross-section on line a; m, Fig. 1.

A is the body of the injector, having the removable cap cl at its upperend. B is the steam'supply pipe, and O C are water-supply pipesconnected at each side of the body A, and communicating with awater-chamber, a. One water-pipe is to be closed by a cap, as shown inFig. 2, when the other is in use.

D is a forcing-valve workingin the nut D, screwed into the body A, andhaving a stutting-box cap, D at its end. The chamber of theforcing-valve is connected by a tube, 12, with the steam-chamber 0, soas to form a t'orcin g-ch am ber.

E is the waste-valve of the lifter; and F is the supply-pipe to theboiler, connected to the body A by the nut F, having a short pipe, F onits under side, to which the overflowvalve G is connected.

This construction and arrangement of the several parts give ready accessto the interior ot' the injector. By removing the cap d at the end ofthe body A access is given to the lifting-tubes, and by unscrewing thenut D, carrying the valve 1), access can be readily had to theforcing-tube; also, by unscrewing the nut F, to which the outlet-tube Fand the valve G are connected, the Water-chamber is made accessible. Theoverflow and Waste valves are ordinary globe-valves attached to the bodyof the feeder.

the forcing-steam tube, connecting the forcing-chamber b with the mainchamber g and entering the tube i, that connects the chamber g with theoutlet-pipe F.

The operation is as follows: Steam, being admitted by the pipe B, passesthrough the lifting-tubes e f, and at the same time steam passes throughthe chamber 1) to the forcingtube It. The steam passing through the tube6 carries the water from the chamber a to the chamber g, and theforcing-valve D being opened, the water is forced through the tube i,and thence to the boiler through the pipe F. In case the valve G isopened, hot water will be supplied to the boiler. hen cold Water :isrequired overflow-valve E is to be opened and the valve G closed, andthe cold water will be drawn Without interfering with the feeding. Nodirt, lime, or other sediment can collect and remain in the chambers.

The apparatus works equally well if it becomes heated as when cold.

Having thus described my invention, I claim as new and desire to secureby Letters Parent 1. In an injector, the combination, with the body A,provided with the lifting-tubes ef, the forcing-tubes h 'i, and thewater-chamber g, of the removable cap (I at the upper end of the body A,the but I), carrying the forcingvalve 1), and the nut F, to which theoutlettube F and the overflow-valve G are attached, arranged at the sideof the body opposite to the forcing valve, substantially as herein shownand described, whereby provision is made for having access to thelifting-tubes, forcing-tubes, and water-chamber, as set forth.

2. In an injector, the combination, with the body A, provided with thechamber 9, and the waste-valve E, of the lifting-tubes 0] and theforcing-tubes h t', arranged as shown, the supply-pipe E, and theoverflow-valve G, substantially as herein shown and described.
